locomotive so that the wheels may be re-,

moved preparatory to repairs and overhauh lng.

The object of the invention is to provide a device for this purpose working on the general principles of a screw jack, which can be conveniently made and installed and which is in particular not liable to get out of order through two ditlerent movements accidentally occurring at the same time.

The invention consists in such a device as can be conveniently installed in or near a locomotive repair shop, the apparatus being adapted for locomotives of different sizes and to be moved under its own power into operative lifting position with reference to such locomotive. This in combination with a lifting mechanism adapted to he adjusted or attached to any part of the locomotive usually at each end.

The invention further consists in the combination with the foregoing of a power controlling device, in the partimilar'form here illustrated a lever so attached to the longitudinally movable parts of the device and the lifting devices that the operator can by operating this single power controlling member operate either one of the foregoing moving mechanisms of the device or leave both of them at rest if he so desires, but that he can not accidentally move both the longitudinal moving mechanism and the lifting mechanism at the same time.

@ther features of the invention will be pointed out later in the specicatiou.

In the drawings, Figure 1 is a side eleva tion of the preferred form of mechanism illustrating the invention. Fig. 2 is a plan view of the parts illustrated in Fig. 1. A

central device for use only in connection with exceedingly long locomotives of the mallet type being also shown thereon. Fig. 3 is an enlarged end detail view taken from approximately the line 3-3 of Fig. Q. Fig.

4 is a sectional detail view of the parts shown in Fig. 3 taken on the line 4-4 of that figure. Fig. 5 is a sectional plan view taken on the line 5-f5, Fig. 4. Fig. (i is an enlarged plan View of the device for use in connection with mullet locomotives referred to at the close of the description of Fig. 2, the parts in this gure being in a different position. Fig. 7 is a vertical elevation taken transversely of the rails showing .the parts of Fig. 6.

The device of this invention is located symmetrically on opposite sides off the, rails l() of4 an ordinary railroad usually located in a locomotive repair shop. Adjacent to one end of these rails are two permanent fixed columns 1Q secured by bolts 14. toa suitable foundation 1'6. J ournaled in bearing 18 in each base 20 of each upright 12 is a line shaft Q2 supported at points along its length by brackets 24 and at `its opposite ends by other brackets Q6. These shafts S22 are longer than any locomotive which can possibly need attention by attend- 'ants using the apparatus and are, as clearly appears, located parallel to each other and parallel to the rails 10.

Near the ends of the shafts Q2 adjacent to the uprights 12, heretofore described, are bevel gears 28 Ameshing with bevel pinions 30 on a cross shaft 32 extending transversely of the rails 10. This shaft 32 is mounted between the bearings 34 and at its end carries a gear 36 meshing with a pinion 37 on motor 38 which is supplied with electric power and through the gearing described drives the two shafts 22. Inside of each base 20, heretofore referred to, is a horizontal worm wheel, not here shown in detail. but similar yto one to be hereafter described, located at the opposite end of the device. This worm wheel meshes with a worm. also not shown, journaled on shaft 22. The end of the worm engages a clutch 39, also not shown in detail, secured to shaft 22 by a feather and operated by a lever 41 whereby by moving the lever in opposite directions the worm may be thrown into or out of connection with the power driven shaft 22. The parts just generally described aie practically identical with other correspending parts at the other end of the shafts 22 which will be fully described. This worm wheel just referred to in each a suitable l *s s es aaai c 2....... i...

ber 90 is a ring 94 let into a 'corresponding base 2t) is rigidly mounted upon a vertical screw 40 mounted in upright supports 12. Connected to these upright screws 40 by screw threads is a cross bar or beam 45 adapted to slip under and engage one end of a locomotive to raise it by the action of The parts at this end of the horizontally. Mounted upon the upper end of the screw j@ members 40 is a small jib crane 44 of ordinary construction having a. trolley 46 also of ordinary construction formingno essential part of thisl invention but very convenvient in working upon small parts of the locomotive standing upon track 10 adjacent to the device, and for handling cross beams. Near the oppositev ends of shafts 22 and parallel therewith and with rails 10 are the screws 40.

device are not movable tuo sets of parallel rails 50 and 52 respectively; 'lhese rails and the mechanism carried by them are identical in every particular. M'ounted upon each pair of rails 50 and 52 is a truck 54 comprising substantially a frame device 56 supported upon wheels 58 adapted to travel along the respective tracks 50 and 52. Each one of these truck frames 56 has attached to it by bolts 60 or other suitable means uprightV supports 62 closely resembling upright supports 12 heretofore referred to. Also carried by each of these upright supports 62 is a screw 64 provided with screw threads, as shown, the bottom of each screw being carried in a step bearing 66 formed in truck frames 56 (see Fig. 4). Each screw64 has threaded upon it a block or nut 70 carrying a non rotatable block 71 on which beam 68 identical in form with beam 42 heretofore referred to rests. This beam 68 may be lifted ed from blocks 71 and removed out of the way when a locomotive moves along track 10. At the upper end of each screw 64 is another jib crane f2-74 identical with the cranes 44-46 and for the same purpose. .e5 They may, if desired, be used to lift beam 68 out of the way of the locomotive.

Rigidly mounted nea-r the bottom of each screw 64 is a'worm wheel 76 meshing with a worm 78 integral with sleeve 8O upon shaft 22. Formed on the sleeves are collars 81 abutting against thrust bearings 82 placed between the collars and the bearings 84 formed in the frame 56. The worm wheel 7 6 heretofore referred to is supported upon balls 86 resting upon a suitable bed 87 in the frame 56, thereby assisting in supporting the screws 64.

As shown, the sleeve extends through one of the bearings 84 and has rigidly con- 60 nected to it clutch member 88 adapted to mesh with opposite clutch member slidably mounted on shaft 22 by means of a spline or feather 92. lnclosing clutch memfrom this ring 94 are pins 98 engaging slots in a yoke lever 102 pivoted at 104 to a bracket 106 on the truck frame 56.

At the opposite end of the truck frame is a bracket 108 having pivoted to it at 110 70 another yoke lever 112 forked, and inclosing clutch member 114. In this lever member 112 are slots 116 like slots 100 heretofore referred to in which are located pins 118, like pins 98, on opposite sides of a ring 75 113 let into clutch member 114. Clutch member 114 meshes with its opposite clutch member 124 which is rigid upon a sleeve 126 loosely mounted upon shaft 22. Rigid on sleeve 126 is a worm 128 meshing with a worm 8o wheel 130 on one of the axles 132 on which truck wheels'58 are mounted. Clutch memf ber 114l is mounted on shaft 22 on a spline exactly like spline 92 heretofore referred'to.

levers 102 and 112 are connected together 85 by a rod 134 so that when the operator takes hold of handle 136 and moves lever 102 to the right from the position of Fig.` the throws clutch member 90 into mesh with clutch member 88, thus causing shaft 22 to 90 rotate worm 128 and thus drive shaft 132, with the result that the truck 54 is propelled along the rails 52 or 50. The throwing in of the clutch just described throws out the clutch member 114 from member 124, thus 95 preventing the rotating of worm wheel 76 and consequently vertical screw 64. 1When he moves lever 102 in the opposite direction or to the left, as seen in Fig. 4, he throws clutch member 124- simultaneously separating members 90 and 88. In the position shown in Fig. 4 neither pair of clutch faces are in engagement with each other, with the y result that the entire mechanism is at rest, and it can be held in that position by the use of a pin 136'1'inserted in a block 138 rigidly attached by screws or bolts v14() to the frame of the truck. j y l j l l-loles 139 and '141,are provided in block o 138 for the insertion of pin 1361 when lever 162 is moved to the. right or left. as heretofore described, thus locking all the parts in said respectiveA positions. Each truck on aeach track 50 and 52 is provided with an 115 independent' .meehanismsuch as this just' described. so that by operating its particular lever 102 it may be controlled independently of the other mechanism of the device.

ln the complete operation ofnthe device the beam 68 is lowered to, about its lowest position and then wholly removed from the screw blocks 71, thereby allowing a locomotive to pass along rails 10 past the parts until the end of the locomotive is over the beam 42. The operator now replaces beam 68 and takes hold of handle 136 on each truck 54 and throws clutch 90 into engage- 65 recess 96 in clutch member 90. Extending ment with clutch member 88, thus starting Jag .s on

clutchv member 114 into engagement with 100'y appearing-at the left hand side vof Fig. 2 125 f wheels 58 of the truck and causing them to move the truck toward the locomotive which is upon the rails 10. When the correct postion is reached under a part ot' the locomotive to be lifted, the operator moves lever 102 to the opposite extreme position, thereby disengagingv clutch S10-88 and engaging clutch 114-124, thus causing screw 64 to rotate and thus lift beam 68 land that end of the locomotive. While this is being done another operator moves lever 41 to throw in clutch 39, thus lifting that end of the locomotive. Then the lifting is ccmpleted motor 38 is stopped. W'hen lowering is to take place the motor is reversed.

fliere exceedingly long locomotives, such `as are now known as mallet locomotives,

are to be lifted in the manner and for the purposes set forth, it is necessary to `provide a supplemental lifting means at the center of the locomotive to prevent its breaking in two under its own weight as it might were it lifted only from the ends as in the case of an ordinary length locomotive. But for the fact that it is somewhat difficult to manuall place a lifting bar identical with bar 68 t irough under the center of the mallet locomotive all of the parts shown at the left hand end of Fig. 2 could be used just as they are there shown at the center of the mullet locomotive, and as a matter of fact, they are so used except for modifications which will rrow be described designed to readily handle the bar 68 under the center of the locomotive. In this modification the bar corresponding to bar 68 is given a numeral 150 and it is separately slidable in a suitable recess clearly appearing in Fig. 6 in the top plate 152 of the piston 151 of a common forln of hydraulic plunger jack vertically slidable in cylinder 156 mounted at the center of the track 10. This jack 154-156 may be operated by any suitable source of power other than water without departing from this invention, so long as the piston 154 is made rotatable sufficiently to allow rotation of bar 150 between a position parallel with the rails 10 shown in dotted lines in Fig. 2 through the yangular position shown in Fig. 6 to the full line position shown in Fig; 2. The ends of the har 150 are provided with U shaped notchesl 160 adapted to fit into, around and receive the ends of screws ltislibstantitillv identical with the screws 64 heretofore described. Each screw 164 is carried and operated by track mechanism 166 movable respectively alo-ng the rails 50 and 52. which track mechanisms are identical with the track and lifting mechanisms shown at the left hand end of Fig. 2.

Lifting device 1511---156 is. as shown in Fig. 7, mounted in'a U shaped trough 168 between the rails 10 so that when the bar l5() has been lswung to the dotted liuc position of Fig. 2, it may be lowered into said recess and below the surface of the rails 10 and thus be out of the way of the locomotive passing along the tracks 10, `to the position where it is to be lifted. When the locomotive reaches this position the operator applies water or any other suitable source of power to the lifting device l5-1-156 and thus causes member 154 to move up to approximately the height illustrated in Fig. l, whereupon workmen by hand take hold of the bar 150 and slowly rotate it throu h the open space between the wheels of tie adjacent locomotive, not here shown, first, to the position of Fig. 6 and finally to the full line position of Fig. 2` in which the notches 16() enga-ge the lifting screws 164. vWhen this position has been reached the operators set the lifting screws 164 on the trucks 166 in operation in exactly the same manner as screws 64, heretofore described, are or would operate, thereby liftingr bar 15() entirely clear of the lifting devices 152--154-156 and bringing it into contact with an adjacent portion of the mallet locomotive. From this point the lifting operation at the center of the locomotive by the devices 166 is identical with the operation of liftin the end of the locomotive by the bar 68. AVhen the work upon the locomotive has been completed and it is desired to return it to the rails the direction of the rotation of the screws 164 is reversed, thereby lowering the bar 150 with the locomotive thereon and finally lowering the bar into its plate 152 on lifting device 154-156. When this position is reached the operators manipulate trucks 166 along the rails 56 and 52 to the position of Fig. 6 and then rotate the bar 15() to theI dotted line position of Fig. 2, after which they manipulate lifting device 154v156 to lower bar 150 downinto the pit 168 heretofore described, in which position it is clear of the locomotive and the locomotive may be moved along the rails 10 Without interference.

If desired, the lifting device 154-156 may be mounted on wheels 170 so that it may be moved lengthwise of the recess between the tracks. In the drawings, this recess between the rails is comparatively narrow. In practice it is the ordinary pit of a locomotive shop.
